If you have a struct that is only internal to the kernel, you can use either u32 or __u32. It will normally be inside a #ifdef __KERNEL__ in the header files. If regular applications use the struct, and it is outside #ifdef __KERNEL__, then it should be __u32, otherwise it could conflict with the application's own typedefs. -- Bob Copeland %% www.bobcopeland.com -- Kernelnewbies: Help each other learn about the Linux kernel.
